Realme appears to be turning a conceptual dream into a commercial reality. After showcasing a 10,000mAh battery concept earlier this year, the company is reportedly working on a mass-market smartphone that packs an even larger 10,001mAh battery.
A mystery device with the model number RMX5107 has surfaced on social media platforms, suggesting that Realme is ready to set a new benchmark for battery endurance in the smartphone industry.
Powered by Android 16 and Next-Gen Software
The leaked “About Device” page reveals that the smartphone is equipped with cutting-edge software and ample storage:
- Operating System: The device runs on Realme UI 7.0, which is based on the upcoming Android 16.
- Storage & RAM: The spotted variant features 12GB of RAM and 256GB of internal storage, likely supported by virtual RAM expansion technology.
- Audio Excellence: The report suggests the inclusion of Hi-Res Audio support, targeting users who prioritize high-quality sound.
Thin Design Meets Massive Power
The biggest challenge with large batteries is maintaining a pocket-friendly design. Realme is reportedly using innovative engineering to keep the phone sleek:
- Mini Diamond Architecture: This layout allows for the “world’s narrowest Android mainboard” (23.4mm), creating more internal space for the battery.
- Ultra-High Silicon Content: The battery features a 10% silicon ratio—the highest in the industry. With an energy density of 887Wh/L, it provides more power without significantly increasing the physical size.
- Slim Profile: Despite the massive capacity, the phone is expected to stay under 8.5mm in thickness and weigh approximately 200g, making it comparable to standard flagship devices.
Competition with Honor Power 2
The news comes shortly after Honor announced the upcoming launch of its Honor Power 2, which is also claimed to feature a 10,000mAh battery. If these leaks are accurate, Realme’s 10,001mAh capacity would give it a slight numerical edge, potentially making it the highest battery capacity smartphone in Realme’s history.
